I purchased my iPad mini 9 days ago and have also purchased the Apple wireless keyboard since then. Today I bought a new case for my mini - it was $9.00 so I couldn't resist. This case is from Bear Motion and I am surprised at the high product quality for the price I paid. Here's what my setup looks like now..
The great thing about a case is that it protects my investment and doubles as a stand. This will definitely come in handy when I take the mini out in public.
EDIT: I just realized that this case has magnets in it that put the iPad mini to sleep and wake it up when you close or open the case.
